Large-scale environmental programs generally commit substantial societal resources, making the evaluation of their actual effects on the relevant outcomes imperative. As the example of the subsidization of energy-saving appliances illustrates, much of the applied environmental economics...

This paper examines the application of quasi-experimental methods in environmental economics. We begin with two observations: i) standard quasi-experimental methods, first applied in other microeconomic fields, typically assume unit-level treatments that do not spill over across units; (ii)...

This study investigates dishonest behavior among cocoa middlemen in Côte d'Ivoire, focusing on the role of observability and financial penalties in deterring such behavior. Using on a modified version of the "die-under-cup task", we examine the cheating behaviors of 151 cocoa middlemen over...

In almost all European Union countries, the gender wage gap is increasing across the wages distribution. In this lecture I briefly survey some recent studies aiming to explain why apparently identical women and men receive such different returns and focus especially on those incorporating...

While politically attractive in order to generate tax revenues, the effects of a financial transaction tax (FTT) are scientifically disputed, not the least because seemingly small details of its implementation may matter a lot. In this paper, we provide experimental evidence on the different...

We conduct a large-scale survey experiment in nine European countries to study how priming a major crisis (COVID-19), common economic interests, and a shared identity influences altruism, reciprocity and trust of EU citizens. We find that priming the COVID-19 pandemic increases altruism and...

Dramatic events can evoke feelings of compassion, fear, or threat, and can affect public opinion regarding controversial issues. Such an event was the drowning of 3-year-old Alan Kurdi, a Syrian boy whose body washed up on a Turkish shore, and was photographed, producing an iconic image that was...

Fungibility of money is a central principle in economics. It implies that any unit of money is substitutable for another and that the composition of income is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many subjects do not treat money as...

In this paper we show that subtle forms of deceit undermine the effectiveness of incentives. We design an experiment in which the principal has an interest in underreporting the true performance difference between the agents in a dynamic tournament. According to the standard approach, rational...
